What's something you'd think I would need to know?
First off, welcome to the message boards, Exemplary! A good bit of advise I would pass on to new posters is to ask you to do a topic search before posting. Recently we have been getting duplicates of the same topic covering the same ground. If you have something new to add to such topics, add it to a post already in existence.
Something that you would surely need to know (but would absolutely come to realize) is that the Message Boards is an awesome place for any pirate looking for further adventure. And that there's a lot of great people here on the boards, all offering up fantastic tips, insight, help, creativity and so much more.
One thing you may or may not know already is that there is a delay from when you click "Submit" to the time your post actually gets posted. The moderators, One-Eyed Jack and Bonnie, need time to look over the incoming posts and make sure they are "acceptable" in nature and content. For this reason posts may take up to 24 hours to actually make an appearance on the boards. This is helpful to know when setting up in game meetings or requesting help from fellow posters, as you'll want to make sure to post a couple days ahead of time to allow for moderation.
I'm sure you'll stumble across other "ooh, that's cool to know" tidbits from here on the boards, so just enjoy your time here, and once again, welcome aboard.
